SPECIFICATION forming part of Letters Patent No. 654,712, dated m 31,1960. Application filed April 16,1900. Serial No. 13,050- :QT mO I ToaZZ whom it may concern:

Be it known that I, ANTONIO CERRUTI, a citizenof the United States, residing at the city and county of San Francisco, in the State of California, have invented certain new and useful Improvements in Cooking-Machines; and I do hereby declare the following to be a full, clear, and exact description of the same.

My invention relates -'to"that "class of machines for cooking fruit,,vegetables, &c., in cans inwhich the can-laden trays are conveyed through thewater by an endless traveling carrier.

My invention consistsin the novel constructions and combinations of the parts of the' machine which I shall hereinafter fully describe and claim and by which I attain the objects of providing'for a steam-trap above the cooking-water, of securing a simple, convenient, and effective construction of trough adapted to readily receive, guide, and discharge the trays and their contents, and directing and conducting a suitable and effct T ive traveling carrier through the trough.

Referring to the accompanying drawings, Figure 1 is a side view, partly in section, of mycooking-machine. Fig. 2 is a top View, the lid H being removed.

A is the trough, consisting of a suitable vessel adapted to contain water. The ends 0t of this trough are slopingly or flaringly upturned, as shown in Fig. 1, in order to facilitate the entrance and exit of the traveling tray-carrier. This carrier consists of side chains B, to which at intervals are secured the cross-flightsb. Within the trough on each side of its bottom and sloping ends are suitable rails a, consisting of flat pieces, upon which the endless side chains of the carrier drag in passing through the trough, thereby avoiding undue wear. The carrier-chainsB pass over suitable terminal sprockets O, and the carrier is driven by suitablemechanism, unnecessary herein to show. The course of the carrier is down over the sloping end ct into the-trough, and by its own weight and that of the can-laden trays upon itit keeps along the bottom, thence up the other sloping end, and down around under the trough to the beginning.

To suitable cross b'races d in the trough are secured the guide-plates D. These may be in any number, butLhave here shown three. They are separated, as shown, and extend longitudinally of the trough and are located at such a distance above the bottom of the trough as to permit the cans E upon the trays F, placed on the carrier, to pass under'them. Their functionis to prevent the cans from risingfrom their trays as they pass through the water in the trough. Being separated these guideplates do not interfere with the free circulation of the watei',--and yet they serve as guides to hold the cans down.

G are cross-partitions, one neareach end of the trough-bottom; butsufficiently removed therefrom to leavesaid ends free'and exposed to permitthe trays tobe placed on the carrier and to be removed therefrom. 'They termihate short ofthe bottom, ending in practice at the guide-plates D and below the level of the water, as shown. In connection with a lid H, placed upon these partitionsgthe latter, together, with the water, form afcover device or trap to provide aninclosed space'or chamber above the water and in which the steam is confined.

The operation "of the machine is as follows: Water being supplied to the trough A, steam is furnished thereto through pipe P, and said steam instead of escaping directlyis confined by the cover device in the space or trap in closedby thewater level, the partition G and the lid H thus securing its best heat efficiency. The attendantplaces the can-laden trays upon the traveling carrier between its flights, and said trays are carried down into and through the water in the trough,the cans being guided under plates D. After the contents of the cans are cooked and as the trays appear at and rise upon the othersloping end of the trough the attendant removes them.

Having thus described my invention, what I claim as new, and-desire to secure by Letters Patent, is i 1. A cookin g-machine comprising asui table trough, a traveling carrier, mounted and adapted to travel through the water in said trough, and to receive and convey the canladen trays tl1erethrough,and a cover or box device above said trough and extending down below the water-level there in, whereby a chamber or trap is formed above the water, for confining the steam.

A cooking-machine comprising a suitable trough, a traveling carrier, mounted and adapted to travel through the water in said trough, and to receive and convey the canladen trays therethrough, cross-partitions 'abbve trough and ex end g wnth reinv below the water-level, but terminating short. of its bottom, and a lid on said partitions, whereby a steam space ortrap is -formedinthe trough, above the water.

3. A cooking-machine comprising a trough,--' having upturned sloping ends, a traveling carrier-adapted to pass down and up said ends and'along the trough-bottom, and to receive and convey the can-laden trays through said 1 rated fare'nough from the sloping ends, to

leave the latter free and exposed, to receive and discharge the trays, said partitions extending down into the trough below the water- .level therein, but terminating short of its bottom, and a lid on said partitions, whereby a {steam space or trap is formed in the trough above the water. 7

A cooking-machine comprising a trough, having upturned sloping ends, a traveling carrier adapted to passdown and up said ends and along the trough-bottom, and to receive and convey the can-laden trays through the trough, fixed separated guide-plates within the trough and'loc'ated high enough above its bottom andends to allow'the cans to pass under them ,said plates beingadapted to-hold said cans down in their trays while passing trough, separated far enoughfrom the sloping ends, to leave the latter free and exposed, to receive and discharge the trays, said partitions extending down into thetrough below the water-level therein, but terminating short ,of its-bottom, and a lid on said partitions, whereby a steam space or trap is formed in .the trough above the water.

8. A cooking-machine comprising a trough having sloping ends, wearing-rails upon each side of the bottom of both trough and ends, a traveling carrier passing over and upon said rails, and adapted to receive and convey the can-laden trays through the trough, fixed separated guide-plates within-the trough and located high enough above its bottom and ends to allow the cans to pass under them, said plates being adapted to hold said cans down in their trays while passing through the water, cross-partitions in the trough, separated far enough from the sloping ends, to leave the latter free and exposed, to receive and discharge the trays, said partitions extending down into the trough below the wafer-level therein, but terminating short of its bottom, and a lid on said partitions, whereby a'steam space or trap is formedin the trough above the water. a In Witness whereof I have hereunto set my hand.
